Description
The M-980-02 is an integrated circuit tone detector for
general purpose use in automatic following of switched
telephone calls. The circuit uses low-power CMOS
techniques to provide the complete filtering and control
required for this function. The basic timing of the M-
980-02 is designed to permit operation with almost any
progress tone system.
The use of integrated circuit techniques allows the
M-980-02 to pack the complete frequency and ampli-
tude portion of call progress following into a single 8-
pin DIP or 16-pin SOIC. A 3.58 MHz crystal-controlled
time base guarantees accuracy and repeatability.
3V/5V operation increases customer flexibility,
improves reliability, and minimizes power consump-
tion.

Note:
Exceeding these ratings may permanently damage the M-980-02.
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.
